Chrysanthemum morifolium response to PAR intensity as indicated through electrical signal
(2012)It is well documented that higher plants respond to environmental stimuli producing electrical signals that are in practise the information carriers in intracellular and intercellular communication. Since the amplitude of ... -
Comparison of several toxicity tests applied to complex wastewaters and mussel biomarkers in receiving waters
(2005)In this study, the complex wastewaters/effluents discharged to coastal regions of Turkey and Greece were sampled, and various toxicity tests were applied. The bioassays used included the assessment of the luminescence ... -
Crop reflectance measurements for nitrogen deficiency detection in a soilless tomato crop
(2018)Early detection of nitrogen deficit stress is essential to effectively and precisely manage crop production under greenhouse conditions. This article demonstrates the use of hyperspectral machine vision as a non-contact ... -
Differences in leaf gas exchange and leaf characteristics between two almond cultivars
(2013)Leaf chlorophyll content, specific leaf weight (SLW), photosynthetic and transpiration rates, stomatal functioning, water use efficiency and quantum yield were assessed during the kernel filling period for two consecutive ... -
Ecosystem modeling of sediment dynamics in the constructed wetland carla in central Greece
(2008)Constructed wetlands are complex dynamic ecosystems. Ecosystem-level modeling of the processes that take place in a constructed wetland is a useful tool for understanding wetland function and structure and for making ... -
Effect of grafting on eggplant leaf gas exchanges under mediterranean greenhouse conditions
(2011)Grafting is an easier and faster approach than plant breeding to take advantage of both existing resistant plants, especially wild cultivars, and high-bred cultivars. The aim of this study was to investigate the changes ... -
Effect of shading on greenhouse energy balance and crop transpiration
(2012)The purpose of this study was to investigate the effect of greenhouse shading and irrigation water salinity on greenhouse microclimate and energy balance and on crop transpiration and leaf photosynthesis. Experiments were ... -
Effects of ozone fumigation on cotton (Gossypium hirsutum L.) morphology, anatomy, physiology, yield and qualitative characteristics of fibers
(2009)This experiment was conducted to study the effect of high ozone concentrations on two cotton (Gossypium hirsutum L.) cultivars. Two cotton cultivars (Roma nos and Allegria) were exposed to con trol (CF < 4 ppb O(3)) and ... -
Effects of reflective mulch on leaf physiology and fruit quality and storability in 'Konservolea' olives
(2012)Reflective mulch (Extenday®) was applied on the tree row to minimize weed growth and soil water evaporation and to increase light availability in the canopy of 'Konservolea' olive trees. The effects of the reflective mulch ... -
Effects of satellite spatial resolution on gross primary productivity estimation through light use efficiency modeling
(2018)Terrestrial Gross Primary Productivity (GPP) describes the total amount of CO2 assimilated by plants in an ecosystem during photosynthesis and is considered the largest flux component of the global carbon cycle. One of the ... -
Influence of Ambient Ozone Pollution on Olive Leaf Gas Exchange Irrigated with Saline Water
(2011)Saline water is often available for irrigation and ambient ozone pollution is significant in the Mediterranean region. These two factors may negatively affect cultivated plant productivity. We studied the effects of a ... -
Influence of deficit irrigation and reflective mulch on 'Konservolea' olive leaf physiology during the growing period
(2011)Scarcity of irrigation water in the Mediterranean region calls for the development of methods to reduce water use for agricultural production. Deficit irrigation and mulching above the irrigated zone could potentially ... -
Lettuce facing microcystins-rich irrigation water at different developmental stages: Effects on plant performance and microcystins bioaccumulation
(2017)This study investigated the microcystins (MCs)-rich irrigation water effect on lettuce of different developmental stages, i.e. during a two months period, covering the whole period from seed germination to harvest at ... -
A novel pattern of leaf movement: The case of Capparis spinosa L.
(2016)A novel type of heliotropic leaf movement is presented for Capparis spinosa L., a summer perennial shrub of Mediterranean and arid ecosystems. In contrast to plants that demonstrate uniform diaheliotropic and/or paraheliotropic ... -
Physiological and biochemical attributes of Mentha spicata when subjected to saline conditions and cation foliar application
(2019)Marginal water, including saline water, has been proposed as an alternative source of irrigation water for partially covering plant water requirements due to scarcity of adequate water supply in hot arid and semi-arid ... -
Zinc uptake, photosynthetic efficiency and oxidative stress in the seagrass Cymodocea nodosa exposed to ZnO nanoparticles
(2019)We characterized zinc oxide nanoparticles (ZnO NPs) by dynamic light scattering (DLS) measurements, and transmission electron microscopy (TEM), while we evaluated photosystem II (PSII) responses, Zn uptake kinetics, and ...
